Add optional typenum-macro that provides tyint and tyuint (resolves #131)

[jerry73204]

This PR provides tyint and tyuint convenient macros to convert integer literals into typenum types, signed and unsigned versions respectively.

It adds an optional feature macros to let users optionally include these macros.

Hey, sorry I have been unresponsive. I did not have the mental energy to look at this repo for a while there.

This is really cool! It would be neat to combine it with the op! macro, but I'm happy to leave that to a later time.

My only concern is that I've never managed a multi-crate repo before. Will crates.io allow publishing a crate with a local optional dependency like this? And, if so, if one depends on typenum from crates.io, will that dependency work?

Or do we need to publish the macro crate separately, and then rely on its crates.io version, to make this happy with the Crates ecosystem?

I made some changes to get ready for merge.

• rebase to master
• doc comments and examples
• remove cargo feature gate

The splitting of multi-crate is due to the limitation of procedure-macro. You'll have to publish both of the crates to crates.io. Make sure uploading the typenum-macro before typenum and the version matches. The path is fine here. You can see an existing example in tch-rs (link).

Thanks again for this and sorry for the delay. I'm going to merge it, and try to see if I can incorporate the op macro.

Edit: Because it makes typenum unpublishable for now, I'm going to merge it to a new branch.

Is it still not ready for merge to main branch?
I don't know what is the barrier, but I tried this and there seems to be no problems.

If there are some problems prevent from merge, please tell me. I try to fix them.

[paholg]

The only issue is that the typenum-macro crate is not published to crates.io.

Created an issue to track it: #188

Thanks for your reply!
Probably, there is no room to contribute for this though, I'm looking forward this release!
